Bitcoin Tuesday is an in-person meetup dedicated to the Bitcoin Revolution, held in Madrid -typically but not only- on the second Tuesday of every month. We are exploring how Bitcoin works from an economic and technical perspective and how it increasingly shapes our world. These are some of the questions we are exploring in the meetup:
- How do Bitcoin and the Lightning Network work?
- How will Bitcoin mining shape the Energy Industry?
- How will Bitcoin shape our world from a social and economic perspective?
Whether you are a Bitcoin Expert or just starting, if you are into Bitcoin, Bitcoin Tuesday is for you. We won't be discussing "Blockchain" as a general-purpose technology, altcoins, NFTs or ICOs. However, we accept criticism and encourage open debate.
Be inspired and learn
At every Bitcoin Tuesday Meetup, we will invite knowledgeable experts to talk about an exciting Bitcoin topic.
Ask Questions
We want to have interesting talks about Bitcoin topics to discuss and learn together. Our sessions are highly interactive, having the opportunity to discuss your questions and exchange your ideas with thought leaders in the Bitcoin industry.
Beers and Networking
After the talks, chat with other fellow Bitcoiners from our diverse community over a Beer. Our audience includes experts and beginners, software and hardware engineers, investors, miners, and Bitcoiners with a product, design, business, and legal backgrounds.
The First Bitcoin Tuesday Meetup took place on December 14th, 2021, organised by Olya. All the participants had the same question: Why isn't there a Bitcoin-dedicated Meetup in Madrid? We couldn't answer that question, but now we can say that Madrid has an excellent one that will foster the city's Bitcoin Community. Onwards!

#77: Capas 2 nativas en Bitcoin (LN+Ark+Spark) con Guerrilla_BTC
MEAT Madrid, Calle Santa Teresa 4,, Madrid, ESBitcoin sí está evolucionando y escalando. Y lo está haciendo sin salir de Bitcoin: con capas 2 100 % nativas que usan únicamente las reglas del consenso Bitcoin (Script, Taproot, timelocks y multisig).
Ninguna introduce una nueva cadena, nueva moneda, soft fork ni federación externa, aunque sí redefinen el concepto de confianza con respecto a la capa 1.
Exploraremos brevemente cómo hemos llegado hasta ellas, cómo funciona cada una y qué asunciones de confianza surgen a la hora de operar:
– Lightning Network (la primera y más madura)
– Spark y Mercury Layer (Statechains)
– Arkade y Second (Ark)
Veremos:
– Cómo funciona cada una y en qué se diferencian
– Por qué no compiten, sino que se complementan mediante swaps atómicos y puentes nativos entre ellas
– Qué wallets reales las usan ya hoy
– Aplicaciones prácticas ya disponibles: stablecoins nativos (sin wrapped tokens), DeFi en Bitcoin, lending, yield, smart wallets, micropagos y remesas instantáneas.
- Debate y evolución sobre modelos de confianza desde LN (confianza mínima) a modelos Trustodial...
